   Establishes a persistent connection to a FrontBase server.

   <span class="function"><strong>fbsql_pconnect()</strong></span> acts very much like
   <span class="function"><a href="function.fbsql-connect.html" class="function">fbsql_connect()</a></span> with two major differences:
  </p>
  <p class="para">
   First, when connecting, the function would first try to find a
   (persistent) link that&#039;s already open with the same host,
   username and password.  If one is found, an identifier for it
   will be returned instead of opening a new connection.
  </p>
  <p class="para">
   Second, the connection to the SQL server will not be closed when
   the execution of the script ends.  Instead, the link will remain
   open for future use.
  </p>
  <p class="para">
   This type of links is therefore called &#039;persistent&#039;.
